My question is :Kepler's 3rd Law states that the squares of the periods of the planets are proportional to the cubes of their average distances from the Sun. This means that a planet that is farther away from the Sun travels

a)faster than a planet that is closer to the Sun

b)more slowly than a planet that is closer to the Sun.

c)at the same speed as a planet that is closer to the Sun

b)more slowly than a planet that is closer to the Sun.
